“…Thus, pigs that received 0.2% of tea polyphenols for 2 weeks showed a significant decrease in total bacteria and bacteroidaceae and a tendency to decrease in C. perfringens. By contrast, a significant increase in Lactobacilli was found 33 . Similarly, two types of GTE were tested in vitro (GTE-1 and GTE-2, polyphenol contents >60% and >80%, respectively) and MICs were determined for diverse pathogenic bacteria.…”

“…31 In an in vitro study conducted by Kemperman et al, 32 the antimicrobial effect of a black tea extract was analyzed by traditional culturing and qPCR, and its impact on microbial community was also assessed by PCR-DGGE and 16S rDNA measurements. 32 Several animal studies conducted in pigs 33 and in calves 34 concluded that tea polyphenols produced an enhancement in animals' intestinal microbiota. Thus, pigs that received 0.2% of tea polyphenols for 2 weeks showed a significant decrease in total bacteria and bacteroidaceae and a tendency to decrease in C. perfringens.…”

Gut microbiota plays a key role in host physiology and metabolism. Indeed, the relevance of a well-balanced gut microbiota composition to an individual´s health status is essential for the person's well-being. Currently, investigations are focused on analyzing the effects of pre-and probiotics as new therapeutic tools to counteract the disruption of intestinal bacterial balance occurring in several diseases. Polyphenols exert a wide range of beneficial health effects. However, although specific attention has been paid in recent years to the function of this "biological entity" in the metabolism of polyphenols, less is known about the modulatory capacity of these bioactive compounds on gut microbiota composition. This review provides an overview of the latest investigations carried out with pure polyphenols, extracts rich in polyphenols and polyphenol-rich dietary sources (such as cocoa, tea, wine, soy products and fruits), and critically discusses the consequences to gut microbiota composition which are produced.

“…Variation in gut microflora associated with lifestyle and diet in humans and other animals has been described (3,10,17,29), but there is a lack of information regarding differences between individuals. In human subjects persistent individual variation in microbial profile, including individual variation in the dominant Lactobacillus sp., has been noted (37,38).…”

We have combined the culture-independent methods of high-throughput sequencing of chaperonin-60 PCR product libraries and quantitative PCR to profile and quantify the small-intestinal microflora of pigs fed diets based on corn, wheat, or barley. A total of 2,751 chaperonin-60 PCR product clones produced from samples of ileum digesta were examined. The majority (81%) of these clones contained sequences independently recovered from all three libraries; 372 different nucleotide sequences were identified, but only 14% of the 372 different sequences were recovered from all three libraries.

“…In addition, some of them have antimicrobial activity and other implications for improving gut health (D'Argenio et al, 2008) that might also result in benefits to animal health and welfare. For example, experimental trials in pigs have demonstrated that administration of polyphenols seems to improve the intestinal microbiota balance, as reflected by a decrease in Clostridium perfringens counts (Hara et al, 1995). To consider the suitability of naringin as a supplement for ruminant nutrition, it is important to evaluate the possible effects of naringin on the ruminal microbial community (Tripoli et al, 2007), since the antiinflammatory activity of naringin, which could help to mitigate the effects of sub-acute ruminal acidosis (associated with high concentrate diets), might be affected as a consequence of the ruminal bacteria metabolism.…”

Naringin dietary supplementation at 0.15% rates does not provide protection against sub-clinical acidosis and does not affect the responses of fattening lambs to road transportation

Forty Assaf fattening lambs (initial age 13 to 15 weeks) offered a diet of barley straw and a commercial concentrate were used to assess the effect of naringin (a type of citrus flavonoid with proven antioxidant, antimicrobial and anti-inflammatory properties in monogastric animals) at a dose of 1.5 g/kg per dry matteron plasma lipid peroxidation thiobarbituric acid reactive substances (TBARS), immune response, ruminal bacterial community and protection provided by the ruminal wall against subclinical acidosis. After 49 days of the experimental diets, lambs were subjected to a 4-h transportation stress period. As expected, TBARS values were significantly increased in all the lambs just after the transportation period, but no effect of naringin was observed. Although naringin lowered red blood cell count, neither the total white blood cells counts nor the production of IFN-g were affected by naringin. No anti-inflammation activity preventing rumenitis was detected, but a clear effect on ruminal bacterial community was observed in lambs consuming naringin. Further experiments, using different doses of naringin might show health benefits of naringin supplementation in lambs, but a clear beneficial effect on health was not readily apparent in this study.
